node.js表达没有响应

Question

I was making a node.js web server on my laptop and it worked without problems. After moving it to my desktop it stopped working because the request was always timing out. After trying to get it to work I decided to try a new script but the request kept timing out.

This is what I tested

const express = require('express')
const app = express()

app.get('/', (req, res) => res.send('Hello World!'))

app.listen(3000, () => console.log('Example app listening on port 3000!'))

I have tried disabling my windows firewall and avast but it didn't do anything. I also reinstalled node.js and still have this problem.

Answer 1

So I thought that maybe I should restart my pc even if I didn't think it would help. But restarting fixed the issue and now it works as it should. Thanks to everyone for helping.

Answer 2

Did you try to add "res.end()"; after the "res.send('Hello World!')" ?
